1. Aerodynamic Lower Air Foil allows air to sweep the work surface and
promote ISO Class 5 air conditions inside the enclosure. See Figure 4-1.
2. Ergonomic Slope of 10 degrees provides maximum visibility and comfort,
reduces glare, thereby minimizing operator fatigue. See Figure 4-1.
3. Internal Depth of 25" provides necessary depth to work inside the
enclosure. See Figure 4-1.
4. Safety Glass Sash with Spring-Loaded Latch has a wiping seal and
features a spring-loaded latch to secure sash open for loading and cleaning.
The sash must be down for normal operation. See Figure 4-1.
5. Utility Ports with Iris allows electrical cords and data cords to pass
through the back of enclosure without leaving a large hole. The enclosure
ships with solid plugs. Iris plugs are included with the User’s Manual. See
Figure 4-1 and 4-2.
6. Optional Guardian™ Airflow Monitor continuously monitors airflow.
An audio/visual alarm alerts the user to low airflow conditions. The
Guardian™ Airflow Monitor is an available option on all Purifier Filtered
PCR Enclosure models. See Figure 4-1 and 4-2.
7. Inherently Safe Impeller has a negative pressure plenum that surrounds
the positive pressure impeller so that if a leak should occur, the unfiltered
air is captured and refiltered. See Figure 4-2.
8. Speed Control regulates the speed of the motorized impeller and is used
by the certifier to validate and adjust the downflow velocity. Located
behind the front panel. See Figures 4-1 and 4-2.
9. Fluorescent Lamp is located above the work area, out of contact with the
clean air. A safety glass window beneath the lamp distributes the light
evenly across the work surface. See Figure 4-1.
10. Filter Pressure Gauge indicates the pressure across the HEPA filter to
help predict HEPA filter loading. See Figure 4-1.
11. Filter Clamping Bolt evenly seals the HEPA filter to the frame of the
enclosure. See Figure 4-1 and 4-2.
12. Control Panel. The control panel, which is located above the sash,
contains the filter pressure gauge, control switches and the electronics. See
Figure 4-1.
13. HEPA (High Efficiency Particulate Air) Filter is rated to remove
99.99% of all particles 0.3 micron in size. See Figure 4-2.
14. Lamp Ballast (Not Shown) for the fluorescent lamp is located behind the
control panel.
15. Variable Digital Timed UV (Ultraviolet) Lamp (Not Shown), allows the
operator to surface disinfect the work area of the enclosure when it is not in
use. The UV light rays will not penetrate the plane of the sash and lower
airfoil. The UV light timer is variable with eight settings in minutes of 5,
10, 15, 30, 60, 120, 240, and infinity. This provides extreme flexibility for
